COMBINED PO LE STRAP AND COLLAR-BUCKLE.

SPECIFICATION forming part of Letters Iatent No. 699,074, dated April 29, 1902. Application filed December 14, 1900. Serial No. 39,911. (No model.)

To all whom it mag concern.-

Be it known that I, ALONZO O. BUTTMAN, a citizen of the United States, and a resident of Columbus City, in the county of Louisa and State of Iowa, have invented a new and Im proved Combined Pole-Strap and Collar- Buckle, of which the following is a full, clear,

and exact description.

The purpose of the invention is to construct a light, simple, durable, and strong buckle especially adapted for use in connection with pole-straps and billets from collars of harness to effect a ready and convenient attachment between the pole and the collars of harness.

Reference is to be had to the accompanying.

drawings, forming apart of this specification,

in which similar characters of reference indi cate corresponding parts in both figures.

Figure 1 is a plan view of the improved buckle, and Fig. 2 is a longitudinal vertical section of the same.

The buckle comprises a main section A and an auxiliary or projecting section B. The main section is larger than the auxiliary or projecting section, and the two sections are separated by a cross-bar 10. The tongue 11 of the buckle is pivoted on this cross-bar 10 and at its free end engages with a roller 12, mounted upon the outer end-bar of the main section A of the buckle. The lower portion of the auxiliary or projecting section B of the buckle is contracted, the contraction commencing at thepoint 13, (shown in Fig. 1,) whicho'ccursabout midway of-the length of the sides of this section of the buckle, thus forming an outer cross-bar 14 and giving to this portionofthe extended section of the buckle astirrup formation, and a roller 15 is mounted on the cross-bar 14..

In the formation of the improved buckle the two sections A and B are at angles to each other, as shown in Fig. 2, so that the main portion A of the buckle may receive a billet or other strap from a horse-collar, while the pole-strap may be passed through the contracted or auxiliary section B of the buckle. By constructing the buckle as shown the strap to which the buckle is attached and which brings the buckle under tension is re moved from the tongue, and therefore it does not cause the tongue to be unduly worn, as in the ordinary buckle, rendering the lifetime of the improved buckle longer than that of the ordinary buckle. The angularity of the buckle-frame serves also to take direct and wearing strain away from the tongue and from the chafe-roller, with which the tongue engages.

' Having thus described my invention, I claim as new and desire to secure by Letters Patent As an article of manufacture, a buckle comprising a middle bar and two end bars, all arranged parallel with each other, the middle bar being the longest and being outside of a plane passing through the other two bars, said middle bar being connected with the longer of said end bars by means of arc-shaped members, and connected with the shorter of said end bars by sinuous members bent three times approximately at right angles, thus forming shoulders for said shorter bar and also forming rounded wear-surfaces adjacent to said shoulders, yet leaving a comparatively wide space tapering by steps and parallel with said shorter bar for facilitating the admission of a strap, a relatively long chafe-roller mounted upon the longer end bar to engagea wide strap, a relatively short chafe-roller mounted upon the shorter end bar to engage a narrow strap, and a tongue mounted upon said middle bar and free to engage the longer of said chafe-rollers.

In testimonywhereof I have signed my name to this specification in the presence of two subscribing witnesses.

ALONZO C. BUTTMAN.
